Watseka Auxiliary Police and Watseka Fire set-up the exercise involving a single-car rollover accident and the four missing occupants of the vehicle. The mock-disaster scene was southeast of Watseka.

Emergency responders set up a staging area at the Iroquois County Courthouse. After a dispatch from the county 9-1-1 Center, a MABAS 37 box alarm activated several participating fire departments. The Mutual Aide Box Alarm brought responders from the Watseka, Milford, Martinton, Ashkum, Crescent-Iroquois, Stockland, and Woodland fire departments.

Communication dispatch service from 9-1-1 and the Emergency Services & Disaster Agency were active participants as well.

River Valley Recycling and Pence Oil also provided assistance with the exercise.
